The City of Denver named the Medina Alert program after Jose Medina, a Denver night club parking valet who was killed by a hit-and-run driver in January 2011. In that case, a cab driver followed the suspect's vehicle and called police, leading to the arrest of the hit-and-run driver.

The City of Aurora began issuing Medina Alerts last year and Arapahoe County will soon join the program.
